Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a National Stage of International Application No. PCT/US2016/012289, filed Jan. 6, 2016, which claims the benefit of U.S. Provisional Application No. 62/100,362, filed Jan. 6, 2015 and U.S. Provisional Application No. 62/159,550, filed May 11, 2015.

FIELD OF THE INVENTION

Provided are methods useful in the treatment of: sphingosine 1-phosphate subtype 1 (S1P₁or SIP1) receptor-associated disorders.

The sphingosine-1-phosphate (SIP) receptors 1-5 constitute a family of G protein-coupled receptors with a seven-transmembrane domain. These receptors, referred to as S1P₁to S1P₅(formerly termed endothelial differentiation gene (EDG) receptor-1, -5, -3, -6, and -8, respectively; Chun et al., Pharmacological Reviews, 54:265-269, 2002), are activated via binding by sphingosine-1-phosphate, which is produced by the sphingosine kinase-catalyzed phosphorylation of sphingosine. S1P₁, S1P₄, and S1P₅receptors activate Gi but not Gq, whereas S1P₂and S1P₃receptors activate both Gi and Gq. The S1P₃receptor, but not the S1P₁receptor, responds to an agonist with an increase in intracellular calcium.

In view of the growing demand for S1P₁agonists useful in the treatment of S1P₁receptor-associated disorders, the compound (R)-2-(7-(4-cyclopentyl-3-(trifluoromethyl)benzyloxy)-1,2,3,4-tetrahydrocyclopenta[b]indol-3-yl)acetic acid (Compound 1, APD334), or a pharmaceutically acceptable salt, solvate, or hydrate thereof,

has emerged as an important new compound, see PCT patent application, Serial No. PCT/US2009/004265 hereby incorporated by reference in its entirety. Compound 1, or a pharmaceutically acceptable salt, solvate, or hydrate thereof, is an investigational drug candidate intended for the treatment of sphingosine 1-phosphate subtype 1 (S1P₁) receptor-associated disorders.

There exists a need for effectively treating individuals who are in need of treatment with Compound 1, or a pharmaceutically acceptable salt, solvate, or hydrate thereof. The present disclosure satisfies this need and provides related advantages as well.

Citation of any reference throughout this application is not to be construed as an admission that such reference is prior art to the present application.

DETAILED DESCRIPTION

As used in the present specification, the following words and phrases are generally intended to have the meanings as set forth below, except to the extent that the context in which they are used indicates otherwise.

Compound 1:

As used herein, “Compound 1” means (R)-2-(7-(4-cyclopentyl-3-(trifluoromethyl)benzyloxy)-1,2,3,4-tetrahydrocyclopenta[b]indol-3-yl)acetic acid including crystalline forms thereof. As a non-limiting example, Compound 1 may be present as an anhydrous, non-solvated crystalline form as described in WO 2010/011316 (incorporated by reference herein in its entirety). As another non-limiting example, an L-arginine salt of Compound 1 may be present as an anhydrous, non-solvated crystalline form as described in WO 2010/011316 and WO 2011/094008 (each of which is incorporated by reference herein in its entirety). As another non-limiting example, a calcium salt of Compound 1 may be present as a crystalline form as described in WO 2010/011316 (incorporated by reference herein in its entirety).

Administering:

As used herein, “administering” means to provide a compound or other therapy, remedy, or treatment. For example, a health care practitioner can directly provide a compound to an individual in the form of a sample, or can indirectly provide a compound to an individual by providing an oral or written prescription for the compound. Also, for example, an individual can obtain a compound by themselves without the involvement of a health care practitioner. Administration of the compound may or may not involve the individual actually internalizing the compound. In the case where an individual internalizes the compound the body is transformed by the compound in some way.

Prescribing:

As used herein, “prescribing” means to order, authorize, or recommend the use of a drug or other therapy, remedy, or treatment. In some embodiments, a health care practitioner can orally advise, recommend, or authorize the use of a compound, dosage regimen or other treatment to an individual. In this case the health care practitioner may or may not provide a prescription for the compound, dosage regimen, or treatment. Further, the health care practitioner may or may not provide the recommended compound or treatment. For example, the health care practitioner can advise the individual where to obtain the compound without providing the compound. In some embodiments, a health care practitioner can provide a prescription for the compound, dosage regimen, or treatment to the individual. For example, a health care practitioner can give a written or oral prescription to an individual. A prescription can be written on paper or on electronic media such as a computer file, for example, on a hand held computer device. For example, a health care practitioner can transform a piece of paper or electronic media with a prescription for a compound, dosage regimen, or treatment. In addition, a prescription can be called in (oral), faxed in (written), or submitted electronically via the internet to a pharmacy or a dispensary. In some embodiments, a sample of the compound or treatment can be given to the individual. As used herein, giving a sample of a compound constitutes an implicit prescription for the compound. Different health care systems around the world use different methods for prescribing and/or administering compounds or treatments and these methods are encompassed by the disclosure.

A prescription can include, for example, an individual's name and/or identifying information such as date of birth. In addition, for example, a prescription can include: the medication name, medication strength, dose, frequency of administration, route of administration, number or amount to be dispensed, number of refills, physician name, physician signature, and the like. Further, for example, a prescription can include a DEA number and/or state number.

A healthcare practitioner can include, for example, a physician, nurse, nurse practitioner, or other related health care professional who can prescribe or administer compounds (drugs) for the treatment of a sphingosine 1-phosphate subtype 1 (S11)₁) receptor-associated disorder. In addition, a healthcare practitioner can include anyone who can recommend, prescribe, administer, or prevent an individual from receiving a compound or drug including, for example, an insurance provider.

Prevent, Preventing, or Prevention:

As used herein, the term “prevent,” “preventing”, or “prevention” such as prevention of a sphingosine 1-phosphate subtype 1 (S11)₁) receptor-associated disorder or the occurrence or onset of one or more symptoms associated with the particular disorder and does not necessarily mean the complete prevention of the disorder. For example, the term “prevent,” “preventing” and “prevention” means the administration of therapy on a prophylactic or preventative basis to an individual who may ultimately manifest at least one symptom of a disease or condition but who has not yet done so. Such individuals can be identified on the basis of risk factors that are known to correlate with the subsequent occurrence of the disease. Alternatively, prevention therapy can be administered without prior identification of a risk factor, as a prophylactic measure. Delaying the onset of at least one symptom can also be considered prevention or prophylaxis.

Treat, Treating, or Treatment:

As used herein the term “treat,” “treating”, or “treatment” means the administration of therapy to an individual who already manifests at least one symptom of a disease or condition or who has previously manifested at least one symptom of a disease or condition. For example, “treating” can include alleviating, abating or ameliorating a disease or condition symptoms, preventing additional symptoms, ameliorating the underlying metabolic causes of symptoms, inhibiting the disease or condition, e.g., arresting the development of the disease or condition, relieving the disease or condition, causing regression of the disease or condition, relieving a condition caused by the disease or condition, or stopping the symptoms of the disease or condition. For example, the term “treating” in reference to a disorder means a reduction in severity of one or more symptoms associated with that particular disorder. Therefore, treating a disorder does not necessarily mean a reduction in severity of all symptoms associated with a disorder and does not necessarily mean a complete reduction in the severity of one or more symptoms associated with a disorder.

Tolerate:

As used herein, an individual is said to “tolerate” a dose of a compound if administration of that dose to that individual does not result in an unacceptable adverse event or an unacceptable combination of adverse events. One of skill in the art will appreciate that tolerance is a subjective measure and that what may be tolerable to one individual may not be tolerable to a different individual. For example, one individual may not be able to tolerate headache, whereas a second individual may find headache tolerable but is not able to tolerate vomiting, whereas for a third individual, either headache alone or vomiting alone is tolerable, but the individual is not able to tolerate the combination of headache and vomiting, even if the severity of each is less than when experienced alone.

Adverse Event:

As used herein, an “adverse event” is an untoward medical occurrence that is associated with treatment with Compound 1 or a pharmaceutically acceptable salt, solvate, or hydrate thereof. In one embodiment, an adverse event is selected from: leukopenia, constipation, diarrhea, nausea, abdominal pain, neutropenia, vomiting, back pain, and menstrual disorder. In one embodiment, an adverse event is heart block, for example, a first degree atrioventricular heart block. In one embodiment, an adverse event is an abnormal pulmonary function test finding, such as an FEV1 below 80%, FVC. In one embodiment, an adverse event is an abnormal liver function test, such as an elevated ALT & AST<2×ULN. In one embodiment, an adverse event is an acute heart rate reduction.

In Need of Treatment and in Need Thereof:

As used herein, “in need of treatment” and “in need thereof” when referring to treatment are used interchangeably to mean a judgment made by a caregiver (e.g. physician, nurse, nurse practitioner, etc. in the case of humans; veterinarian in the case of animals, including non-human mammals) that an individual or animal requires or will benefit from treatment. This judgment is made based on a variety of factors that are in the realm of a caregiver's expertise, but that includes the knowledge that the individual or animal is ill, or will become ill, as the result of a disease, condition or disorder that is treatable by the compounds of the invention. Accordingly, the compounds of the invention can be used in a protective or preventive manner; or compounds of the invention can be used to alleviate, inhibit or ameliorate the disease, condition or disorder.

Individual:

As used herein, “individual” means any animal, including mammals, preferably mice, rats, other rodents, rabbits, dogs, cats, swine, cattle, sheep, horses, or primates and most preferably humans.

Desensitization of the Heart:

As used herein, “desensitization of the heart” means the absence of an acute heart rate reduction after drug administration.

Acute Heart Rate Reduction:

As used herein, “acute heart rate reduction” means a heart rate decrease from normal sinus rhythm of, for example, 10 or more beats per minute (bpm), such as less than about 5 bpm, e.g., less than about 4 bpm or less than about 3 bpm or less than 2 bpm, that is maximal within a few hours, for example 1-3 hours, after drug administration, and thereafter the heart rate returns towards the pre-dose value.

Normal Sinus Rhythm:

As used herein, “normal sinus rhythm” means the sinus rhythm of the individual when not undergoing treatment. The evaluation of normal sinus rhythm is within the ability of a physician. A normal sinus rhythm will generally give rise to a heart rate in the range from 60-100 bpm.

Dose:

As used herein, “dose” means a quantity of Compound 1, or a pharmaceutically acceptable salt, solvate, or hydrate thereof, given to the individual for treating or preventing the disease or disorder at one specific time.

Standard Dose:

As used herein, “standard dose” means the dose of Compound 1, or a pharmaceutically acceptable salt, solvate, or hydrate thereof, that is given to the individual for treating or preventing the disease or disorder. In some embodiments, administration of the standard dose achieves a target reduction in peripheral blood lymphocyte counts, e.g., a reduction in baseline of at least 35%, such as at least 40%, such as at least 45%, such as at least 50%, such as at least 55%, such as at least 60%, such as at least 65%, such as at least 70%. In some embodiments, administration of the standard dose achieves a reduction in baseline of about 35% to about 70%, such as about 40% to about 65%, such as about 50% to about 65%. In some embodiments, administration of the standard dose achieves target peripheral blood lymphocyte counts, e.g., less than 1000 lymphocytes per microliter, such as 400-800 lymphocytes per microliter. The target dose may vary depending on the nature and severity of the disease to be treated.

One or More Doses:

As used herein, “one or more doses” as used in the phrase “one or more doses, each of which is less than the standard dose” means one or a plurality of doses of Compound 1, or a pharmaceutically acceptable salt, solvate, or hydrate thereof, that is given to the individual during the first period of time and each is less than the standard dose. In some embodiments, the first period comprises a plurality of subperiods wherein a different dose of Compound 1, or a pharmaceutically acceptable salt, solvate, or hydrate thereof, is given to the individual in each of the subperiods. In some embodiments, administration of one or more doses during the first period will have an effect on peripheral blood lymphocyte counts. In some embodiments, administration of one or more doses during the first period will not have effect on peripheral blood lymphocyte counts.

Fasted Individual:

As used herein, “fasted individual” means an individual who has not eaten any food, i.e., has fasted for at least 6-8 hours, such as about 8 hours, before the administration of Compound 1, or a pharmaceutically acceptable salt, hydrate, or solvate thereof, and who does not eat any food and continues to fast for at least 1 hour after the administration of Compound 1, or a pharmaceutically acceptable salt, hydrate, or solvate thereof. In certain embodiments, the individual may also refrain from ingesting certain non-food substances during the fasting period. For example, in certain embodiments the individual does not ingest any supplements and/or drugs during the fasting period. In certain embodiments, the individual does not ingest any high calorie liquids during the fasting period. In certain embodiments, the individual does not ingest any liquids other than water during the fasting period. In certain embodiments, the individual may ingest small amounts of low calorie beverages, such as tea, coffee, or diluted juices.

Mayo Clinic Score (MCS):

As used herein, “Mayo Clinic Score” or “MCS” means an instrument designed to measure disease activity of ulcerative colitis and consists of 4 subscores: stool frequency, rectal bleeding, findings of flexible proctosigmoidoscopy, and physician global assessment with each component ranging from 0 to 3 (0=normal, 1=mild, 2=moderate, 3=severe). Total score therefore ranges from 0 to 12, with a higher score indicating more severe disease. The 6-point Mayo score is based on stool frequency and rectal bleeding PROs collected daily using electronic patient diaries and excludes the findings on endoscopy and the physician's global assessment. The physician's global assessment acknowledges the three other criteria findings of the MCS, the individual's daily record of abdominal discomfort and general sense of well-being, and other observations, such as physical findings and the individual's performance.

As used herein, “mildly to moderately active ulcerative colitis” means ulcerative colitis characterized by a 4-component MCS of 4 to 10.

Moderately to Severely Active Ulcerative Colitis:

As used herein, “moderately to severely active ulcerative colitis” means ulcerative colitis characterized by a 3-component MCS of 4 to 9 including an endoscopic subscore of ≥2 and a rectal bleeding score of ≥1. The 3-component MCS uses 3 of the 4 components of the complete MCS (endoscopic findings, rectal bleeding, and stool frequency).

Clinical Remission:

As used herein, “clinical remission” with respect to ulcerative colitis means a 3-component Mayo Clinic score as follows: an endoscopy score (using flexible proctosigmoidoscopy) of 0 or 1, a rectal bleeding score of 0, and a stool frequency score of 0 or 1 with a decrease of ≥1 point from baseline subscore.

Clinical Response:

As used herein, “clinical response” with respect to ulcerative colitis means a reduction in the 3-component Mayo Clinic score of ≥2 points and a decrease of ≥30% from baseline with an accompanying decrease in rectal bleeding subscore of ≥1 or absolute rectal bleeding score of 0 or 1.

As used herein, “agonist” means a moiety that interacts with and activates a G-protein-coupled receptor, such as the S1P₁receptor, such as can thereby initiate a physiological or pharmacological response characteristic of that receptor. For example, an agonist activates an intracellular response upon binding to the receptor, or enhances GTP binding to a membrane. In certain embodiments, an agonist of the invention is an S1P₁receptor agonist that is capable of facilitating sustained S1P₁receptor internalization (see e.g., Matloubian et al., Nature, 427, 355, 2004).

Antagonist:

As used herein, “antagonist” means a moiety that competitively binds to the receptor at the same site as an agonist (for example, the endogenous ligand), but which does not activate the intracellular response initiated by the active form of the receptor and can thereby inhibit the intracellular responses by an agonist or partial agonist. An antagonist does not diminish the baseline intracellular response in the absence of an agonist or partial agonist.

Inverse Agonist:

As used herein, “inverse agonist” means a moiety that binds to the endogenous form of the receptor or to the constitutively activated form of the receptor and which inhibits the baseline intracellular response initiated by the active form of the receptor below the normal base level of activity which is observed in the absence of an agonist or partial agonist, or decreases GTP binding to a membrane. In some embodiments, the baseline intracellular response is inhibited in the presence of the inverse agonist by at least 30%. In some embodiments, the baseline intracellular response is inhibited in the presence of the inverse agonist by at least 50%. In some embodiments, the baseline intracellular response is inhibited in the presence of the inverse agonist by at least 75%, as compared with the baseline response in the absence of the inverse agonist.

Hydrate:

As used herein, “hydrate” means a compound of the invention or a salt thereof, that further includes a stoichiometric or non-stoichiometric amount of water bound by non-covalent intermolecular forces.

Safety Population:

As used herein, “safety population” means all randomized subjects who received study medication. See, e.g., Tables 3 and 4 below.

Solvate:

As used herein, “solvate” means a compound of the invention or a salt, thereof, that further includes a stoichiometric or non-stoichiometric amount of a solvent bound by non-covalent intermolecular forces. Preferred solvents are volatile, non-toxic, and/or acceptable for administration to humans in trace amounts.

The compounds according to the invention may optionally exist as pharmaceutically acceptable salts including pharmaceutically acceptable acid addition salts prepared from pharmaceutically acceptable non-toxic acids including inorganic and organic acids. Representative acids include, but are not limited to, acetic, benzenesulfonic, benzoic, camphorsulfonic, citric, ethenesulfonic, dichloroacetic, formic, fumaric, gluconic, glutamic, hippuric, hydrobromic, hydrochloric, isethionic, lactic, maleic, malic, mandelic, methanesulfonic, mucic, nitric, oxalic, pamoic, pantothenic, phosphoric, succinic, sulfiric, tartaric, oxalic, p-toluenesulfonic and the like, such as those pharmaceutically acceptable salts listed by Berge et al., Journal of Pharmaceutical Sciences, 66:1-19 (1977), incorporated herein by reference in its entirety.

The acid addition salts may be obtained as the direct products of compound synthesis. In the alternative, the free base may be dissolved in a suitable solvent containing the appropriate acid and the salt isolated by evaporating the solvent or otherwise separating the salt and solvent. The compounds of this invention may form solvates with standard low molecular weight solvents using methods known to the skilled artisan.

It is understood that when the phrase “pharmaceutically acceptable salts, solvates and hydrates” or the phrase “pharmaceutically acceptable salt, solvate, or hydrate” is used when referring to Compound 1, it embraces pharmaceutically acceptable solvates and/or hydrates of Compound 1, pharmaceutically acceptable salts of Compound 1, as well as pharmaceutically acceptable solvates and/or hydrates of pharmaceutically acceptable salts of Compound 1. It is also understood that when the phrase “pharmaceutically acceptable solvates and hydrates” or the phrase “pharmaceutically acceptable solvate or hydrate” is used when referring to Compound 1 that are salts, it embraces pharmaceutically acceptable solvates and/or hydrates of such salts.

It will be apparent to those skilled in the art that the dosage forms described herein may comprise, as the active component, either Compound 1 or a pharmaceutically acceptable salt or as a solvate or hydrate thereof. Moreover, various hydrates and solvates of Compound 1 and their salts will find use as intermediates in the manufacture of pharmaceutical compositions. Typical procedures for making and identifying suitable hydrates and solvates, outside those mentioned herein, are well known to those in the art; see for example, pages 202-209 of K. J. Guillory, “Generation of Polymorphs, Hydrates, Solvates, and Amorphous Solids,” in: Polymorphism in Pharmaceutical Solids, ed. Harry G. Britain, Vol. 95, Marcel Dekker, Inc., New York, 1999. Accordingly, one aspect of the present disclosure pertains to methods of prescribing and/or administering hydrates and solvates of Compound 1 and/or its pharmaceutical acceptable salts, that can be isolated and characterized by methods known in the art, such as, thermogravimetric analysis (TGA), TGA-mass spectroscopy, TGA-Infrared spectroscopy, powder X-ray diffraction (XRPD), Karl Fisher titration, high resolution X-ray diffraction, and the like. There are several commercial entities that provide quick and efficient services for identifying solvates and hydrates on a routine basis. Example companies offering these services include Wilmington PharmaTech (Wilmington, Del.), Avantium Technologies (Amsterdam) and Aptuit (Greenwich, Conn.).

The present disclosure includes all isotopes of atoms occurring in the present compounds, salts, solvates, and hydrates. Isotopes include those atoms having the same atomic number but different mass numbers. One aspect of the present invention includes every combination of one or more atoms in the present compounds, salts, solvates, and hydrates that is replaced with an atom having the same atomic number but a different mass number. One such example is the replacement of an atom that is the most naturally abundant isotope, such as ¹H or ¹²C, found in one the present compounds, salts, solvates, and hydrates, with a different atom that is not the most naturally abundant isotope, such as ²H or ³H (replacing ¹H), or ¹¹C, ¹³C, or ¹⁴C (replacing ¹²C). When such a replacement has taken place it is commonly referred to as being isotopically-labeled. Isotopic-labeling of the present compounds, salts, solvates, and hydrates can be accomplished using any one of a variety of different synthetic methods know to those of ordinary skill in the art and they are readily credited with understanding the synthetic methods and available reagents needed to conduct such isotopic-labeling. By way of general example, and without limitation, isotopes of hydrogen include ²H (deuterium) and ³H (tritium). Isotopes of carbon include ¹¹C, ¹³C, and ¹⁴C. Isotopes of nitrogen include ¹³N and ¹⁵N. Isotopes of oxygen include ¹⁵O, ¹²O, and ¹⁸O. An isotope of fluorine includes ¹⁸F. An isotope of sulfur includes ³⁵S. An isotope of chlorine includes ³⁶Cl. Isotopes of bromine include ⁷⁵Br, ⁷⁶Br, ⁷⁷Br, and ⁸²Br. Isotopes of iodine include ¹²³I, ¹²⁴I, ¹²⁵I, and ¹³¹I. Another aspect of the present invention includes compositions, such as, those prepared during synthesis, preformulation, and the like, and pharmaceutical compositions, such as, those prepared with the intent of using in a mammal for the treatment of one or more of the disorders described herein, comprising one or more of the present compounds, salts, solvates, and hydrates, wherein the naturally occurring distribution of the isotopes in the composition is perturbed. Another aspect of the present invention includes compositions and pharmaceutical compositions comprising the compounds, salts, solvates, and hydrates, as described herein wherein the salt is enriched at one or more positions with an isotope other than the most naturally abundant isotope. Methods are readily available to measure such isotope perturbations or enrichments, such as, mass spectrometry, and for isotopes that are radio-isotopes additional methods are available, such as, radio-detectors used in connection with HPLC or GC.

Compounds of the present invention can be converted to “prodrugs.” The term “prodrugs” means compounds that have been modified with specific chemical groups known in the art and that when administered into an individual undergo biotransformation to give the parent compound. Prodrugs can thus be viewed as compounds of the invention containing one or more specialized non-toxic protective groups used in a transient manner to alter or to eliminate a property of the compound. In one general aspect, the “prodrug” approach is utilized to facilitate oral absorption. A thorough discussion is provided in T. Higuchi and V. Stella, Prodrugs as Novel Delivery Systems Vol. 14 of the A.C.S. Symposium Series; and in Bioreversible Carriers in Drug Design, ed. Edward B. Roche, American Pharmaceutical Association and Pergamon Press, 1987, both of which are hereby incorporated by reference in their entirety.

S1P receptor agonists having agonist activity on the S1P₁receptor have been shown to rapidly and reversibly induce lymphopenia (also referred to as peripheral lymphocyte lowering (PLL); Hale et al., Bioorg. Med. Chem. Lett., 14:3351-3355, 2004). This is attended by clinically useful immunosuppression by virtue of sequestering T- and B-cells in secondary lymphoid tissue (lymph nodes and Peyer's patches) and thus apart from sites of inflammation and organ grafts (Rosen et al., Immunol. Rev., 195:160-177, 2003; Schwab et al., Nature Immunol., 8:1295-1301, 2007). This lymphocyte sequestration, for example in lymph nodes, is thought to be a consequence of concurrent agonist-driven functional antagonism of the S1P₁receptor on T-cells (whereby the ability of S1P to mobilize T-cell egress from lymph nodes is reduced) and persistent agonism of the S1P₁receptor on lymph node endothelium (such that barrier function opposing transmigration of lymphocytes is increased) (Matloubian et al., Nature, 427:355-360, 2004; Baumruker et al., Expert Opin. Investig. Drugs, 16:283-289, 2007). It has been reported that agonism of the S1P₁receptor alone is sufficient to achieve lymphocyte sequestration (Sanna et al., J. Biol. Chem., 279:13839-13848, 2004) and that this occurs without impairment of immune responses to systemic infection (Brinkmann et al., Transplantation, 72:764-769, 2001; Brinkmann et al., Transplant. Proc., 33:530-531, 2001).

That agonism of endothelial S1P₁receptors has a broader role in promoting vascular integrity is supported by work implicating the S1P₁receptor in capillary integrity in mouse skin and lung (Sanna et al., Nat. Chem. Biol., 2:434-441, 2006). Vascular integrity can be compromised by inflammatory processes, for example as may derive from sepsis, major trauma and surgery so as to lead to acute lung injury or respiratory distress syndrome (Johan Groeneveld, Vascul. Pharmacol., 39:247-256, 2003).

An exemplary S1P receptor agonist having agonist activity on the S1P₁receptor is FTY720 (fingolimod), an immunosuppressive agent that has undergone clinical trials (Martini et al., Expert Opin. Investig. Drugs, 16:505-518, 2007) and was recently approved by the FDA for the treatment of individuals with relapsing forms of multiple sclerosis (MS) to reduce the frequency of clinical exacerbations and to delay the accumulation of physical disability. FTY720 acts as a prodrug which is phosphorylated in vivo; the phosphorylated derivative is an agonist for S1P₁, S1P₃, S11)₄and S1P₅receptors (but not the S1P₂receptor) (Chiba, Pharmacology & Therapeutics, 108:308-319, 2005). FTY720 has been shown to rapidly and reversibly induce lymphopenia; Hale et al., Bioorg. Med. Chem. Lett., 14:3351-3355, 2004). This is attended by clinically useful immunosuppression by virtue of sequestering T- and B-cells in secondary lymphoid tissue (lymph nodes and Peyer's patches) and thus apart from sites of inflammation and organ grafts (Rosen et al., Immunol. Rev., 195:160-177, 2003; Schwab et al., Nature Immunol., 8:1295-1301, 2007).

In clinical trials, FTY720 elicited an adverse event (i.e., transient asymptomatic bradycardia) which may be due to its agonism of the S1P₃receptor (Budde et al., J. Am. Soc. Nephrol., 13:1073-1083, 2002; Sanna et al., J. Biol. Chem., 279:13839-13848, 2004; Ogawa et al., BBRC, 361:621-628, 2007).

FTY720 has been reported to have therapeutic efficacy in at least: a rat model for autoimmune myocarditis and a mouse model for acute viral myocarditis (Kiyabayashi et al., J. Cardiovasc. Pharmacol., 35:410-416, 2000; Miyamoto et al., J. Am. Coll. Cardiol., 37:1713-1718, 2001); mouse models for inflammatory bowel disease including colitis (Mizushima et al., Inflamm. Bowel Dis., 10:182-192, 2004; Deguchi et al., Oncology Reports, 16:699-703, 2006; Fujii et al., Am. J. Physiol. Gastrointest. Liver Physiol., 291:G267-G274, 2006; Daniel et al., J. Immunol., 178:2458-2468, 2007); a rat model for progressive mesangioproliferative glomerulonephritis (Martini et al., Am. J. Physiol. Renal Physiol., 292:F1761-F1770, 2007); a mouse model for asthma, suggested to be primarily through the S1P₁receptor on the basis of work using the S1P₁receptor agonist SEW2871 (Idzko et al., J. Clin. Invest., 116:2935-2944, 2006); a mouse model for airway inflammation and induction of bronchial hyperresponsiveness (Sawicka et al., J. Immunol., 171; 6206-6214, 2003); a mouse model for atopic dermatitis (Kohno et al., Biol. Pharm. Bull., 27:1392-1396, 2004); a mouse model for ischemia-reperfusion injury (Kaudel et al., Transplant. Proc., 39:499-502, 2007); a mouse model for systemic lupus erythematosus (SLE) (Okazaki et al., J. Rheumatol., 29:707-716, 2002; Herzinger et al., Am. J. Clin. Dermatol., 8:329-336, 2007); rat models for rheumatoid arthritis (Matsuura et al., Int. J. Immunopharmacol., 22:323-331, 2000; Matsuura et al., Inflamm. Res., 49:404-410, 2000); a rat model for autoimmune uveitis (Kurose et al., Exp. Eye Res., 70:7-15, 2000); mouse models for type I diabetes (Fu et al., Transplantation, 73:1425-1430, 2002; Maki et al., Transplantation, 74:1684-1686, 2002; Yang et al., Clinical Immunology, 107:30-35, 2003; Maki et al., Transplantation, 79:1051-1055, 2005); mouse models for atherosclerosis (Nofer et al., Circulation, 115:501-508, 2007; Keul et al., Arterioscler. Thromb. Vasc. Biol., 27:607-613, 2007); a rat model for brain inflammatory reaction following traumatic brain injury (TBI) (Zhang et al., J. Cell. Mol. Med., 11:307-314, 2007); and mouse models for graft coronary artery disease and graft-versus-host disease (GVHD) (Hwang et al., Circulation, 100:1322-1329, 1999; Taylor et al., Blood, 110:3480-3488, 2007). In vitro results suggest that FTY720 may have therapeutic efficacy for β-amyloid-related inflammatory diseases including Alzheimer's disease (Kaneider et al., FASEB J., 18:309-311, 2004). KRP-203, an S1P receptor agonist having agonist activity on the S1P₁receptor, has been reported to have therapeutic efficacy in a rat model for autoimmune myocarditis (Ogawa et al., BBRC, 361:621-628, 2007). Using the S1P₁receptor agonist SEW2871, it has been shown that agonism of endothelial S1P₁receptors prevents proinflammatory monocyte/endothelial interactions in type I diabetic vascular endothelium (Whetzel et al., Circ. Res., 99:731-739, 2006) and protects the vasculature against TNFα-mediated monocyte/endothelial interactions (Bolick et al., Arterioscler. Thromb. Vasc. Biol., 25:976-981, 2005).

Additionally, FTY720 has been reported to have therapeutic efficacy in experimental autoimmune encephalomyelitis (EAE) in rats and mice, a model for human multiple sclerosis (Brinkmann et al., J. Biol. Chem., 277:21453-21457, 2002; Fujino et al., J. Pharmacol. Exp. Ther., 305:70-77, 2003; Webb et al., J. Neuroimmunol., 153:108-121, 2004; Rausch et aL, J. Magn. Reson. Imaging, 20:16-24, 2004; Kataoka et al., Cellular & Molecular Immunology, 2:439-448, 2005; Brinkmann et al., Pharmacology & Therapeutics, 115:84-105, 2007; Baumruker et al., Expert Opin. Investig. Drugs, 16:283-289, 2007; Balatoni et al., Brain Research Bulletin, 74:307-316, 2007). Furthermore, FTY720 has been found to have therapeutic efficacy for multiple sclerosis in clinical trials. In Phase II clinical trials for relapsing-remitting multiple sclerosis, FTY720 was found to reduce the number of lesions detected by magnetic resonance imaging (MRI) and clinical disease activity in individuals with multiple sclerosis (Kappos et al., N. Engl. J. Med., 355:1124-1140, 2006; Martini et al., Expert Opin. Investig. Drugs, 16:505-518, 2007; Zhang et al., Mini-Reviews in Medicinal Chemistry, 7:845-850, 2007; Brinkmann, Pharmacology & Therapeutics, 115:84-105, 2007). Phase III clinical studies with FTY720 in individuals with remitting-relapsing multiple sclerosis have been reported (Brinkmann, Pharmacology & Therapeutics, 115:84-105, 2007; Baumruker et al., Expert. Opin. Investig. Drugs, 16:283-289, 2007; Dev et al., Pharmacology and Therapeutics, 117:77-93, 2008).

FTY720 has also been reported to have anti-viral activity. Specific data has been presented in the lymphocytic choriomeningitis virus (LCMV) mouse model, wherein the mice were infected with either the Armstrong or the clone 13 strain of LCMV (Premenko-Lanier et al., Nature, 454, 894, 2008).

FTY720 has been reported to impair migration of dendritic cells infected with Francisella tularensis to the mediastinal lymph node, thereby reducing the bacterial colonization of it. Francisella tularensis is associated with tularemia, ulceroglandular infection, respiratory infection and a typhoidal disease (E. Bar-Haim et al., PLoS Pathogens, 4(11): e1000211, published 21 Nov. 2008; info:doi/10.1371/journal.ppat.1000211, 2008).

It has also been recently reported that a short-term high dose of FTY720 rapidly reduced ocular infiltrates in experimental autoimmune uveoretinitis. When given in the early stages of ocular inflammation, FTY720 rapidly prevented retinal damage. It was reported that FTY720 not only prevented infiltration of target organs, but also reduce existing infiltration (Raveney et al., Arch. Ophthalmol., 126(10), 1390, 2008).

It has been reported that treatment with FTY720 relieved ovariectomy-induced osteoporosis in mice by reducing the number of mature osteoclasts attached to the bone surface. The data provided evidence that S1P controlled the migratory behavior of osteoclast precursors, dynamically regulating bone mineral homeostasis (Ishii et al., Nature, advance online publication, 8 Feb. 2009, doi:10.1038/nature07713).

Agonism of the S1P₁receptor has been implicated in enhancement of survival of oligodendrocyte progenitor cells. Survival of oligodendrocyte progenitor cells is a required component of the remyelination process. Remyelination of multiple sclerosis lesions is considered to promote recovery from clinical relapses (Miron et al., Ann. Neurol., 63:61-71, 2008; Coelho et al., J. Pharmacol. Exp. Ther., 323:626-635, 2007; Dev et al., Pharmacology and Therapeutics, 117:77-93, 2008). It also has been shown that the S1P₁receptor plays a role in platelet-derived growth factor (PDGF)-induced oligodendrocyte progenitor cell mitogenesis (Jung et al., Glia, 55:1656-1667, 2007).

Agonism of the S1P₁receptor has also been reported to mediate migration of neural stem cells toward injured areas of the central nervous system (CNS), including in a rat model of spinal cord injury (Kimura et al., Stem Cells, 25:115-124, 2007).

Agonism of the S1P₁receptor has been implicated in the inhibition of keratinocyte proliferation (Sauer et al., J. Biol. Chem., 279:38471-38479, 2004), consistent with reports that S1P inhibits keratinocyte proliferation (Kim et al., Cell Signal, 16:89-95, 2004). The hyperproliferation of keratinocytes at the entrance to the hair follicle, which can then become blocked, and an associated inflammation are significant pathogenetic factors of acne (Koreck et al., Dermatology, 206:96-105, 2003; Webster, Cutis, 76(2 Suppl):4-7, 2005).

FTY720 has been reported to have therapeutic efficacy in inhibiting pathologic angiogenesis, such as that as may occur in tumor development. Inhibition of angiogenesis by FTY720 is thought to involve agonism of the S1P₁receptor (Oo et al., J. Biol. Chem., 282; 9082-9089, 2007; Schmid et al., J. Cell Biochem., 101:259-270, 2007). FTY720 has been reported to have therapeutic efficacy for inhibiting primary and metastatic tumor growth in a mouse model of melanoma (LaMontagne et al., Cancer Res., 66:221-231, 2006). FTY720 has been reported to have therapeutic efficacy in a mouse model for metastatic hepatocellular carcinoma (Lee et al., Clin. Cancer Res., 11:84588466, 2005).

It has been reported that oral administration of FTY720 to mice potently blocked VEGF-induced vascular permeability, an important process associated with angiogenesis, inflammation, and pathological conditions such as sepsis, hypoxia, and solid tumor growth (T Sanchez et al., J. Biol. Chem., 278(47), 47281-47290, 2003).

Cyclosporin A and FK506 (calcineurin inhibitors) are drugs used to prevent rejection of transplanted organs. Although they are effective in delaying or suppressing transplant rejection, classical immunosuppressants such as cyclosporin A and FK506 are known to cause several undesirable side effects including nephrotoxicity, neurotoxicity, β-cell toxicity and gastrointestinal discomfort. There is an unmet need in organ transplantation for an immunosuppressant without these side effects which is effective as a monotherapy or in combination with a classical immunosuppressant for inhibiting migration of, e.g., alloantigen-reactive T-cells to the grafted tissue, thereby prolonging graft survival.

FTY720 has been shown to have therapeutic efficacy in transplant rejection both as a monotherapy and in synergistic combination with a classical immunosuppressant, including cyclosporin A, FK506, and RAD (an mTOR inhibitor). It has been shown that, unlike the classical immunosuppressants cyclosporin A, FK506 and RAD, FTY720 has efficacy for prolonging graft survival without inducing general immunosuppression, and this difference in drug action is believed to be relevant to the synergism observed for the combination (Brinkmann et al., Transplant Proc., 33:530-531, 2001; Brinkmann et al., Transplantation, 72:764-769, 2001).

Agonism of the S1P₁receptor has been reported to have therapeutic efficacy for prolonging allograft survival in mouse and rat skin allograft models (Lima et al., Transplant Proc., 36:1015-1017, 2004; Yan et al., Bioorg. & Med. Chem. Lett., 16:3679-3683, 2006). FTY720 has been reported to have therapeutic efficacy for prolonging allograft survival in a rat cardiac allograft model (Suzuki et al., Transpl. Immunol., 4:252-255, 1996). FTY720 has been reported to act synergistically with cyclosporin A to prolong rat skin allograft survival (Yanagawa et al., J. Immunol., 160:5493-5499, 1998), to act synergistically with cyclosporin A and with FK506 to prolong rat cardiac allograft survival, and to act synergistically with cyclosporin A to prolong canine renal allograft survival and monkey renal allograft survival (Chiba et al., Cell Mol. Biol., 3:11-19, 2006). KRP-203, an S1P receptor agonist has been reported to have therapeutic efficacy for prolonging allograft survival in a rat skin allograft model and both as monotherapy and in synergistic combination with cyclosporin A in a rat cardiac allograft model (Shimizu et al., Circulation, 111:222-229, 2005). KRP-203 also has been reported to have therapeutic efficacy in combination with mycophenolate mofetil (MMF; a prodrug for which the active metabolite is mycophenolic acid, an inhibitor of purine biosynthesis) for prolonging allograft survival both in a rat renal allograft model and in a rat cardiac allograft model (Suzuki et al., J. Heart Lung Transplant, 25:302-209, 2006; Fujishiro et al., J. Heart Lung Transplant, 25:825-833, 2006). It has been reported that an agonist of the S1P₁receptor, AUY954, in combination with a subtherapeutic dose of RAD001 (Certican/Everolimus, an mTOR inhibitor) can prolong rat cardiac allograft survival (Pan et al., Chemistry & Biology, 13:1227-1234, 2006). In a rat small bowel allograft model, FTY720 has been reported to act synergistically with cyclosporin A to prolong small bowel allograft survival (Sakagawa et al., Transpl. Immunol., 13:161-168, 2004). FTY720 has been reported to have therapeutic efficacy in a mouse islet graft model (Fu et al., Transplantation, 73:1425-1430, 2002; Liu et al., Microsurgery, 27:300-304; 2007) and in a study using human islet cells to evidence no detrimental effects on human islet function (Truong et al., American Journal of Transplantation, 7:2031-2038, 2007).

FTY720 has been reported to reduce the nociceptive behavior in the spared nerve injury model for neuropathic pain which does not depend on prostaglandin synthesis (O. Costu et al., Journal of Cellular and Molecular Medicine 12(3), 995-1004, 2008).

FTY720 has been reported to impair initiation of murine contact hypersensitivity (CHS). Adoptive transfer of immunized lymph node cells from mice treated with FTY720 during the sensitization phase was virtually incapable of inducing CHS response in recipients (D. Nakashima et al., J. Investigative Dermatology (128(12), 2833-2841, 2008).

It has been reported that prophylactic oral administration of FTY720 (1 mg/kg, three times a week), completely prevented the development of experimental autoimmune myasthenia gravis (EAMG) in C57BL/6 mice (T. Kohono et al., Biological & Pharmaceutical Bulletin, 28(4), 736-739, 2005).

In one embodiment, the present invention encompasses compounds which are agonists of the S1P₁receptor having selectivity over the S1P₃receptor. Using a combined chemical approach with S1P receptor null mice, Sanna et al. reported that sustained bradycardia was induced by nonselective S1P receptor immunosuppressive agonists in wild-type mice but was abolished in S1P₃−/− mice whereas an S1P₁-selective agonist did not produce bradycardia. Thus suggesting that the S1P₃receptor, and not the S1P₁receptor, was responsible for bradycardia (Sanna et al., J. Biol. Chem., 279:13839-13848, 2004). Therefore, an S1P₁receptor agonist selective over at least the S1P₃receptor has advantages over current therapies by virtue of an enhanced therapeutic window, allowing better tolerability with higher dosing and thus improving efficacy as therapy. The present invention encompasses Compound 1 (and pharmaceutically acceptable salts, hydrates, and solvates thereof) which is an agonist of the S1P₁receptor and has exhibited no or substantially no bradycardia in male Sprague-Dawley® rats (see WO2010/011316, Example 9).

A phase 1 study with Compound 1 was conducted with single dosing at 0.1 mg, 0.35 mg, 1 mg, 3 mg, and 5 mg. Compound 1 was administered as the L-arginine salt. Lower doses of 0.1 mg through 3 mg were well tolerated by subjects with only minor adverse events reported, the most common of which were headache and contact dermatitis. A dose-dependent reduction in heart rate was seen in all doses >0.35 mg, however, no adverse events related to bradycardia were reported at doses lower than the 5 mg dose. Dose limiting adverse events were observed at the dose of 5 mg, with 3 (50%) subjects experiencing 4 AEs of bradycardia with first or second degree atrioventricular (AV) block, which resulted in discontinuation of dose escalation. The maximum tolerated dose in the study was 3 mg. There were no deaths or serious adverse events in the study.

There were no other clinically significant safety issues with respect to vital signs, ECGs, pulmonary function tests, ophthalmoscopy, or clinical laboratory tests with the exception of expected pharmacological effects on peripheral blood lymphocyte counts. Dosing at the 3 and 5 mg induced a dose responsive decline in the absolute number of peripheral blood B cells, T cells, NK cells, and all T cell subsets except TEM cells. Total peripheral blood lymphocyte (PBL) counts were reduced by 2-4 hours after dosing, reaching a nadir by hour 8 which persisted for 24 hours with recovery to baseline over the next 4 days. PBL counts were reduced by ˜40% and ˜55% at the 3 mg and 5 mg dose levels. TEM cells do not express CCR7 and are able to recirculate independently of S1P receptor expression. These findings are therefore consistent with the anticipated pharmacodynamic effects of S1P receptor agonists in preclinical studies and in humans (Gergely et al., Br J Pharmacol 167(5):1035-1047, 2012; Brossard et al., Br J Clin Pharmacol 2013 Apr. 18. doi:10.1111/bcp.12129. [Epub ahead of print] PubMed PMID: 23594176, and Kovarik et al., J Clin Pharmacol 44(5):532-537, 2004.)

S1P₁receptor agonists are useful to treat or prevent conditions where suppression of the immune system or agonism of the S1P₁receptor is in order, such as diseases and disorders mediated by lymphocytes, transplant rejection, autoimmune diseases and disorders, inflammatory diseases and disorders, and conditions that have an underlying defect in vascular integrity or that relate to angiogenesis such as may be pathologic.

Also provided are pharmaceutical compositions comprising a standard dose of Compound 1, or, a pharmaceutically acceptable salt, a hydrate or solvate thereof and, optionally, one or more pharmaceutically acceptable carriers. Also provided are pharmaceutical compositions comprising an initial dose of Compound 1, or, a pharmaceutically acceptable salt, a hydrate or solvate thereof, optionally, one or more pharmaceutically acceptable carriers. The carrier(s) must be “acceptable” in the sense of being compatible with the other ingredients of the formulation and not overly deleterious to the recipient thereof.

In some embodiments, Compound 1, or, a pharmaceutically acceptable salt, a hydrate or solvate thereof, is administered as a raw or pure chemical, for example as a powder in capsule formulation.

In some embodiments, Compound 1, or, a pharmaceutically acceptable salt, a hydrate or solvate thereof, is formulated as a pharmaceutical composition further comprising one or more pharmaceutically acceptable carriers.

Pharmaceutical compositions may be prepared by any suitable method, typically by uniformly mixing the active compound(s) with liquids or finely divided solid carriers, or both, in the required proportions and then, if necessary, forming the resulting mixture into a desired shape.

Conventional excipients, such as binding agents, fillers, acceptable wetting agents, tabletting lubricants and disintegrants may be used in tablets and capsules for oral administration. Liquid preparations for oral administration may be in the form of solutions, emulsions, aqueous or oily suspensions and syrups. Alternatively, the oral preparations may be in the form of dry powder that can be reconstituted with water or another suitable liquid vehicle before use. Additional additives such as suspending or emulsifying agents, non-aqueous vehicles (including edible oils), preservatives and flavorings and colorants may be added to the liquid preparations. Parenteral dosage forms may be prepared by dissolving the compound of the invention in a suitable liquid vehicle and filter sterilizing the solution before filling and sealing an appropriate vial or ampule. These are just a few examples of the many appropriate methods well known in the art for preparing dosage forms.

The compounds described herein can be formulated into pharmaceutical compositions using techniques well known to those in the art. Suitable pharmaceutically acceptable carriers, outside those mentioned herein, are known in the art; for example, see Remington, The Science and Practice of Pharmacy, 20^thEdition, 2000, Lippincott Williams & Wilkins, (Editors: Gennaro et al.)

Pharmaceutical formulations include those suitable for oral, rectal, nasal, topical (including buccal and sub-lingual), vaginal or parenteral (including intramuscular, sub-cutaneous, and intravenous) administration or in a form suitable for administration by inhalation, insufflation or by a transdermal patch. Transdermal patches dispense a drug at a controlled rate by presenting the drug for absorption in an efficient manner with a minimum of degradation of the drug. Typically, transdermal patches comprise an impermeable backing layer, a single pressure sensitive adhesive, and a removable protective layer with a release liner. One of ordinary skill in the art will understand and appreciate the techniques appropriate for manufacturing a desired efficacious transdermal patch based upon the needs of the artisan.

The compounds of the invention, together with a conventional adjuvant, carrier, or diluent, may thus be placed into the form of pharmaceutical formulations and unit dosages thereof and in such form may be employed as solids, such as tablets or filled capsules, or liquids such as solutions, suspensions, emulsions, elixirs, gels, or capsules filled with the same, all for oral use; in the form of suppositories for rectal administration; or in the form of sterile injectable solutions for parenteral (including subcutaneous) use. Such pharmaceutical compositions and unit dosage forms thereof may comprise conventional ingredients in conventional proportions, with or without additional active compounds or principles and such unit dosage forms may contain any suitable effective amount of the active ingredient commensurate with the intended daily dosage range to be employed.

For oral administration, the pharmaceutical composition may be in the form of, for example, a tablet, capsule, suspension or liquid. The pharmaceutical composition is preferably made in the form of a dosage unit containing a particular amount of the active ingredient. Examples of such dosage units are capsules, tablets, powders, granules or suspensions, with conventional additives such as lactose, mannitol, corn starch or potato starch; with binders such as crystalline cellulose, cellulose derivatives, acacia, corn starch or gelatins; with disintegrators such as corn starch, potato starch or sodium carboxymethyl-cellulose; and with lubricants such as talc or magnesium stearate. The active ingredient may also be administered by injection as a composition wherein, for example, saline, dextrose or water may be used as a suitable pharmaceutically acceptable carrier.

For preparing pharmaceutical compositions from the compounds of the present invention, the suitable pharmaceutically acceptable carrier can be either solid, liquid or a mixture of both. Solid form preparations include powders, tablets, pills, capsules, cachets, suppositories, and dispersible granules. A solid carrier can be one or more substances which may also act as diluents, flavoring agents, solubilizers, lubricants, suspending agents, binders, preservatives, tablet disintegrating agents, or encapsulating materials.

In powders, the carrier is a finely divided solid which is in a mixture with the finely divided active component.

In tablets, the active component is mixed with the carrier having the necessary binding capacity in suitable proportions and compacted to the desired shape and size.

The powders and tablets may contain varying percentage amounts of the active compound. A representative amount in a powder or tablet may be from 0.5 to about 90 percent of the active compound. However, an artisan would know when amounts outside of this range are necessary. Suitable carriers for powders and tablets include magnesium carbonate, magnesium stearate, talc, sugar, lactose, pectin, dextrin, starch, gelatin, tragacanth, methylcellulose, sodium carboxymethyl cellulose, a low melting wax, cocoa butter, and the like. The term “preparation” is includes the formulation of the active compound with encapsulating material as carrier providing a capsule in which the active component, with or without carriers, is surrounded by a carrier, which is thus in association with it. Similarly, cachets and lozenges are included. Tablets, powders, capsules, pills, cachets, and lozenges can be used as solid forms suitable for oral administration.

For preparing suppositories, a low melting wax, such as an admixture of fatty acid glycerides or cocoa butter, is first melted and the active component is dispersed homogeneously therein (e.g., by stirring). The molten homogenous mixture is then poured into convenient sized molds, allowed to cool and thereby to solidify.

Formulations suitable for vaginal administration may be presented as pessaries, tampons, creams, gels, pastes, foams or sprays containing in addition to the active ingredient such carriers as are known in the art to be appropriate.

Liquid form preparations include solutions, suspensions, and emulsions, for example, water or water-propylene glycol solutions. For example, parenteral injection liquid preparations can be formulated as solutions in aqueous polyethylene glycol solution. Injectable preparations, for example, sterile injectable aqueous or oleaginous suspensions may be formulated according to the known art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation may also be a sterile injectable solution or suspension in a nontoxic parenterally acceptable diluent or solvent, for example, as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil may be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid find use in the preparation of injectables.

The compounds according to the present invention may thus be formulated for parenteral administration (e.g. by injection, for example bolus injection or continuous infusion) and may be presented in unit dose form in ampoules, pre-filled syringes, small volume infusion or in multi-dose containers with an added preservative. The pharmaceutical compositions may take such forms as suspensions, solutions, or emulsions in oily or aqueous vehicles and may contain formulatory agents such as suspending, stabilizing and/or dispersing agents. Alternatively, the active ingredient may be in powder form, obtained by aseptic isolation of sterile solid or by lyophilization from solution, for constitution with a suitable vehicle, e.g. sterile, pyrogen-free water, before use.

Aqueous formulations suitable for oral use can be prepared by dissolving or suspending the active component in water and adding suitable colorants, flavors, stabilizing and thickening agents, as desired.

Aqueous suspensions suitable for oral use can be made by dispersing the finely divided active component in water with viscous material, such as natural or synthetic gums, resins, methylcellulose, sodium carboxymethyl cellulose, or other well-known suspending agents.

Also included are solid form preparations which are intended to be converted, shortly before use, to liquid form preparations for oral administration. Such liquid forms include solutions, suspensions and emulsions. These preparations may contain, in addition to the active component, colorants, flavors, stabilizers, buffers, artificial and natural sweeteners, dispersants, thickeners, solubilizing agents, and the like.

For topical administration to the epidermis the compounds according to the invention may be formulated as ointments, creams or lotions, or as a transdermal patch.

Ointments and creams may, for example, be formulated with an aqueous or oily base with the addition of suitable thickening and/or gelling agents. Lotions may be formulated with an aqueous or oily base and will in general also contain one or more emulsifying agents, stabilizing agents, dispersing agents, suspending agents, thickening agents, or coloring agents.

Formulations suitable for topical administration in the mouth include lozenges comprising the active agent in a flavored base, usually sucrose and acacia or tragacanth; pastilles comprising the active ingredient in an inert base such as gelatin and glycerin or sucrose and acacia; and mouthwashes comprising the active ingredient in a suitable liquid carrier.

Solutions or suspensions are applied directly to the nasal cavity by conventional means, for example with a dropper, pipette or spray. The formulations may be provided in single or multi-dose form. In the latter case of a dropper or pipette, this may be achieved by the individual administering an appropriate, predetermined volume of the solution or suspension. In the case of a spray, this may be achieved for example by means of a metering atomizing spray pump.

Administration to the respiratory tract may also be achieved by means of an aerosol formulation in which the active ingredient is provided in a pressurized pack with a suitable propellant. If the compounds of the present invention or pharmaceutical compositions comprising them are administered as aerosols (e.g., nasal aerosols, by inhalation), this can be carried out, for example, using a spray, a nebulizer, a pump nebulizer, an inhalation apparatus, a metered inhaler or a dry powder inhaler. Pharmaceutical forms for administration of the compounds of the present invention as an aerosol can be prepared by processes well known to the person skilled in the art. Solutions or dispersions of the compounds of the present invention or a pharmaceutically acceptable salt, solvate, hydrate or derivative thereof in water, water/alcohol mixtures or suitable saline solutions, for example, can be employed using customary additives (e.g., benzyl alcohol or other suitable preservatives), absorption enhancers for increasing the bioavailability, solubilizers, dispersants and others and, if appropriate, customary propellants (e.g., carbon dioxide, CFCs, such as, dichlorodifluoromethane, trichlorofluoromethane, dichlorotetrafluoroethane, and the like). The aerosol may conveniently also contain a surfactant such as lecithin. The dose of drug may be controlled by provision of a metered valve.

In formulations intended for administration to the respiratory tract, including intranasal formulations, the compound will generally have a small particle size for example of the order of 10 microns or less. Such a particle size may be obtained by means known in the art, for example by micronization. When desired, formulations adapted to give sustained release of the active ingredient may be employed.

Alternatively the active ingredients may be provided in the form of a dry powder (e.g., a powder mix of the compound in a suitable powder base such as lactose, starch, starch derivatives such as hydroxypropylmethyl cellulose and polyvinylpyrrolidone (PVP)). Conveniently the powder carrier will form a gel in the nasal cavity. The powder composition may be presented in unit dose form (e.g., capsules, cartridges) as for gelatin or blister packs from which the powder may be administered by means of an inhaler.

The pharmaceutical preparations are preferably in unit dosage forms. In such form, the preparation is subdivided into unit doses containing appropriate quantities of the active component. The unit dosage form can be a packaged preparation, the package containing discrete quantities of preparation, such as packeted tablets, capsules and powders in vials or ampoules. Also, the unit dosage form can be a capsule, tablet, cachet, or lozenge itself, or it can be the appropriate number of any of these in packaged form.

In some embodiments, the compositions are tablets or capsules for oral administration.

In some embodiments, the compositions are liquids for intravenous administration.

Some embodiments of the present invention include a method of producing a pharmaceutical composition for “combination-therapy” comprising admixing at least one compound according to any of the compound embodiments disclosed herein, together with at least one known pharmaceutical agent as described herein and a pharmaceutically acceptable carrier.

It is noted that when S1P₁receptor agonists are utilized as active ingredients in a pharmaceutical composition, these are not intended for use only in humans, but in other non-human mammals as well. Indeed, recent advances in the area of animal health-care mandate that consideration be given for the use of active agents, such as S1P₁receptor agonists, for the treatment of an S1P₁receptor-associated disease or disorder in companionship animals (e.g., cats, dogs, etc.) and in livestock animals (e.g., cows, chickens, fish, etc.). Those of ordinary skill in the art are readily credited with understanding the utility of such compounds in such settings.

a first number of daily units of a pharmaceutical composition comprising an initial dose of Compound 1, or a pharmaceutically acceptable salt, hydrate, or solvate thereof, is in an amount equivalent to about 1 mg or less of Compound 1, and

Also provided is a titration package for enabling compliance with a regimen of changing dosage of medication over a period of time for the treatment of inflammatory bowel disease, wherein the medication is (R)-2-(7-(4-cyclopentyl-3-(trifluoromethyl)benzyloxy)-1,2,3,4-tetrahydrocyclopenta[b]indol-3-yl)acetic acid (Compound 1), or a pharmaceutically acceptable salt, hydrate, or solvate thereof, the package comprising:

a first number of daily units of a pharmaceutical composition comprising an initial dose of Compound 1, or a pharmaceutically acceptable salt, hydrate, or solvate thereof, is in an amount equivalent to about 0.5 mg or less of Compound 1, and

a second number of daily units of a pharmaceutical composition comprising a standard dose of Compound 1, or a pharmaceutically acceptable salt, hydrate, or solvate thereof, is in an amount equivalent to about 1.0 to about 2.0 mg of Compound 1.

Further embodiments include the embodiments disclosed in the following Examples, which is not to be construed as limiting in any way.

Cohort 1 was dosed with 0.7 mg (by administering two 0.35 mg formulations) for 21 days. Cohort 2 was dosed with 1.35 mg (by administering both a 0.35 mg formulation and a 1 mg formulation) for 21 days. Cohort 3 was dosed with 2.0 mg for 21 days. Cohort 4 was dosed with 0.35 mg for 7 days and then with 2.0 mg for 14 days. Cohort 5 was dosed with 0.5 for 7 days and then with 3.0 mg (by administering both a 1 mg formulation and a 2 mg formulation) for 14 days.

The following safety assessments were conducted: physical examinations with ophthalmoscopy, clinical laboratory tests (serum chemistry, coagulation, and urinalysis), vital signs, continuous telemetry (12 lead ECG), safety ECGs, pulmonary function testing (PFT), serum protein electrophoresis (SPEP) and serum immunoelectrophoresis (IEP), and adverse event reporting.

The L-arginine salt of Compound 1 was tolerated at all dose levels. The most common adverse events included contact dermatitis and leukopenia, followed by constipation, diarrhea, nausea, and abdominal pain. The contact dermatitis observed is consistent with what is generally seen with the adhesive tape from the ECG leads used in the study and did not occur more frequently in the treated group. The majority of adverse events were mild. There were no other clinically significant safety issues with respect to vital signs, ECGs, PFTs, ophthalmoscopy, or clinical laboratory tests. No subjects were discontinued due to an adverse event. No SAEs or deaths occurred during the study.

No second degree heart block was found. Three subjects developed new (not present before dosing) 1^stdegree atrioventricular block: 1 subject in placebo group, 1 subject in 2 mg group, and 1 subject in 0.5, 3 mg group. One subject (1.35 mg dose) had mildly abnormal reproducible (NCS) pulmonary function test findings (FEV1 below 80%, FVC) post-dose.

Two subjects had mildly abnormal non-clinically significant post-treatment liver function tests (elevated alanine aminotransferase (ALT) & aspartate aminotransferase (AST)≤2× upper limit of normal (ULN)): 1 subject in 2 mg group and 1 subject in 0.5 escalating to 3 mg group.

No clinically significant change from baseline in ophthalmoscopy findings were found on exam. FIG. 1 shows observed lymphocyte counts (10³/μl) in the safety population. FIG. 2 shows observed neutrophil counts (10³/μl) in the safety population. Table 5 shows a summary of percent change from baseline at day 21 in lymphocytes (10³/μl): safety population.
